Determination
of the TGW is essential to enable accurate control of the seed rate
when sowing to obtain the correct plant population target.

Rapid
Seed Viability Embryo Test (Vitascope)
|
|
A test
for cereals. It provides a quick indication of the seed's potential
germination and will show which seeds will or will not produce growth.
Seeds are soaked in a chemical solution for 20 minutes, Viable embryos
are stained red, dead embryos do not stain.
|
|
This test
will not detect abnormal growths caused by drying heat damage or mechanical
damage. Badly sprouted seeds are recorded as dead.
|
|
This test
cannot be performed on treated samples.

Stained
Embryo Analysis (SEA)
|
|
A test
for cereals. Seeds are soaked in warm water for 4 hours to facilitate
removal of entire embryos. Embryos are then soaked overnight in a
chemical
solution and are then disected and examined individually under a microscope.
Viable parts of the embryo can then be determined and also possible
damage to the embryo which may cause abnormal growth.
|
|
This test
cannot be performed on treated samples.

A test
for cereals, oilseed rape, peas & beans
|
|
Two replicates
of 100 seeds are grown under optimum conditions for a fixed period.
Each seedling is then checked, and seedlings likely to produce healthy
adult plants are counted. Each seedling is also tested for any abnormality
which could prevent it from developing, giving an accurate guide to
field potential.
|
|
This method
by which germination is determined is the same as for certified seed,
and is approved by DEFRA and prescribed by OSTS and the ISTA.

A test
for barley only. The number of infected embryos is determined by microscopic
examination after a chemical extraction process. The level of infection
will help decide which seed treatment is needed.

A test
for peas and beans to assess the infection level of this seed-borne
disease in the seed lot and to help decide which seed treatment is needed.
|
|
Do not
treat seed lots with high levels of infection.
